We study rare events data, binary dependent variables with dozens to thousands of times fewer ones (events, such as wars, vetoes, cases of political activism, or epidemiological infections) than zeros ("nonevents"). In many literatures, these variables have proven difficult to explain and...

WhatIf is an R package that implements the methods for evaluating counterfactuals introduced in King and Zeng (2006a) and King and Zeng (2006b). It offers easy-to-use techniques for assessing a counterfactual's model dependence without having to conduct sensitivity testing over specified classes...

Some of the most important phenomena in international conflict are coded as “rare events”: binary dependent variables with dozens to thousands of times fewer events, such as wars and coups, than “nonevents.” Unfortunately, rare events data are difficult to explain and predict, a problem...

We study rare events data, binary dependent variables with dozens to thousands of times fewer ones (events, such as wars, vetoes, cases of political activism, or epidemiological infections) than zeros (quot;noneventsquot;). In many literatures, these variables have proven difficult to explain...

We address the problem that occurs when inferences about counterfactuals -- predictions, quot;what ifquot; questions, and causal effects -- are attempted far from the available data. The danger of these extreme counterfactuals is that substantive conclusions drawn from statistical models that...

We thank Scott de Marchi, Christopher Gelpi, and Jeffrey Grynaviski (2003; hereinafter dGG) for their careful attention to our work (Beck, King, and Zeng, 2000; hereinafter BKZ) and for raising some important methodological issues that we agree deserve readers' attention. We are pleased that dGG's...

In response to the data-based measures of model dependence proposed in King and Zeng (2006), Sambanis and Michaelides (2008) propose alternative measures that rely upon assumptions untestable in observational data. If these assumptions are correct, then their measures are appropriate and ours,...

We address a well-known but infrequently discussed problem in the quantitative study of international conflict: Despite immense data collections, prestigious journals, and sophisticated analyses, empirical findings in the literature on international conflict are often unsatisfying. Many...

Some of the most important phenomena in international conflict are coded s "rare events data," binary dependent variables with dozens to thousands of times fewer events, such as wars, coups, etc., than "nonevents". Unfortunately, rare events data are difficult to explain and predict, a problem...
